Reaction Steps
A mixture of 1-(4-Isopropoxy-2-methyl-5-nitro-phenyl)-ethanone (0.788 g, 3.32 mmol), ethyleneglycol (1.8 mL), and p-toluenesulfonic acid monohydrate (6.3 mg) in 60 mL of benzene is heated at reflux with a Dean-Stark trap for 18 hrs. The reaction mixture is diluted with 100 mL of ethyl acetate and successively washed with 100 mL each of aqueous saturated NaHCO3, H2O, and saturated brine. The organic phase is dried over anhydrous Na2SO4, filtered and concentrated in vacuo, affording 2-(4-Isopropoxy-2-methyl-5-nitro-phenyl)-2-methyl-[1,3]dioxolane as yellow crystals. MS (ES+): 282.2 (MH+).
